Hey

asking on behalf of a mate with an R32 GTS-T

Recently on occasion his car has been running poorly and sounding like a boxer. It's intermittent and happens while driving, sometimes from cold/cool, sometimes after driving for a while and then will sometimes just go away.

Any ideas of what to check? He has recently replaced coil packs but it is not really an ignition breakdown issue from the way it's behaving, perhaps a loose wire (but which?)

Cheers for any help,

Clinton

100% one of the coil packs or a spark plug. A RB sounds like a WRX when it drops a cylinder and runs on 4 or 5.

Easy way to check, when the car is idling, unplug the coilpack on cylinder one. If the note of the exhaust changes it's not that one. Plug it back in and go to the next. Keep doing this for all six until one of them doesn't change the cars sound. Thats your dropped cylinder.

Doesnt the 1st post say he just recently replaced the coil packs??

Hope you replaced em with Splitfires....

Just thoroughly go over all the ignition wiring & see if you can find anything. Does sound like a general coil pack issue.

They were replaced with a known good second hand set, so it could well be that the "new" ones are now failing also.

Will try those suggestions, thanks.

      Shoota's R33 GT-R RB30/26

      By Shoota_77 · Posted

      Hi guys, long time no post as per usual! It's been a busy year so far, the biggest thing being a new job.  After 28 years in the automotive industry I decided it was time for a change.  I was losing faith in the industry and where it's heading.  Now in a completely different industry (electrical) working for a company that manufacture water pump contollers.  Not as sexy as cars but it's an interesting,  challenging industry. I now don't work Saturdays which is a bonus!  It's still 50-55 hours a week but having Saturdays ack after 28 years of working them is awesome!   No news on the GT-R but i did decide to add some more JDM goodness into my life....           1990 300 ZX.  She's not perfect but for a 35 year old car she ain't bad!  Just going to tidy it up a bit and enjoy it.  It's currently auto but will start stockpiling everything for a manual swap. It WILL distract me even further from the GT-R but im hoping not for too long! It somewhat proves a 6'8" freak can fit in a 300 ZX.  Sort of...  I drove it home from the previous owners house in Melbourne via Black Spur and Merton Gap (2 awesome bits of Victorian twisty road) and it was amazing!  Handles so well!!!   I don't think it would be worthy of a full build page but I'll post up some of the upgrades here if anyone is interested?  Cheers guys!

      End game is to: - Remove all the slop from old worn parts - Adjust setup so that the wheels actually fit and the car is drivable (currently it is not because of the extreme rubbing on the guards).   Progress over the last couple of days, removed the rear hubs! Next steps: - Buy bushings - Replace bushings/bearings on hub - Reinstall

      A few random issues have popped up since my last update. My WMI pressure sensor failed within about 10 minutes of it seeing liquid. It was a 20$ China special, so I'm not surprised. My name brand replacement should arrive today.  My power steering assist also decided to crap out last weekend. The usual, works for about 60 seconds after starting the car then I lose it. I dusted off my old copy of NDS and connected to the HICAS ECU. Code 4 for assist solenoid.... I tested the solenoid and it's fine.  I knew the day where my HICAS ecu would crap out would come, and I welcome it. It was the last HICAS part on the car that is now in the bin. I've ordered an SSR and I will control the power steering solenoid with my Haltech ecu. It will be nice to have proper speed referenced assist again after all these years.
